    The picture quality on these was good too. As VHS goes. Over the time I was using VHS, I had a Sharp, a Samsung, a very similar to this one Panasonic (a little bit older than this one), a JVC and a Sony. By far the Panasonic was my favorite. I never had any problems with it with daily use for years. I think I got it around 1996 and probably used it almost every day until DVD started to take over. The Sony was a little nicer in the bells and whistles but I wasn't the biggest fan of it's picture quality. The JVC was one of the SVHS ET machines but I honestly didn't see much difference in the picture between that one and a normal VHS.

    16:27 Ooops, tactile switch decapitated... Yes, these with the Z mechanism are nice machines, just don't use them for tapes that were recorded with bad tape path alignment. Those plastic bases for the guide rollers will only allow a few realignments before the thread wears out. I was sure they have brass inserts for the threads, but they don't! That crazy fine pitch alignment thread is in the plastic itself. I found that out when I bought a Panasonic SVHS machine in which the alignment was off and as I touched the guide roller with the screwdriver it lowered by millimeters without turning it. I had to transplant the guides from a 2-head donor machine. Some early and/or higher-end models had metal roller bases with this same Z mechanism, but they are quite rare. Also, on some of these (seemingly mostly the non-Japanese ones), the rubber on the pinch roller is often cracked, and that was already the case even 10 years ago with machines from the early '00s, some were less than 10 years old back then.

    Mr. Volts, did l miss your front panel reassembly? Standard procedure: You keep the door flap in the "up" position with your thumb, then snap on the whole front panel. If you do not, the inner "lifting Lever" would be in the down position, thus unable to lift the door on tape ejection. 😮 please 🙏 correct me if l am in error. Best regards. MJ in B'dos 😊

    The big cam gear sometimes breaks from down under, because of a black-type factory lubricant present from factory. It turns into glue over time. Or the metal levers connecting under the cam gear can bend and snap for the same reason. Usually made in Slovakia or Hungary. I always regease these units when I come accross them.

    I don't think Panasonic had a factory in Hungary. Their European factories that I'm aware of were in Slovakia/Czech Republic and Poland, and maybe one in the UK. Hungary had Sony, Samsung and Philips factories, but no Panasonic. Samsung is still there, but Sony and Philips are long gone.

    ​@@speed_rider362 I can't find info about any Hungarian Panasonic factory. Panasonic Hungary exists, but they only do sales according to their site, and no reference about them making anything ever here. Well, in the '80s they assembled NV-430 VCRs in the Hungarian Orion factory, but that was a one time gig only for that one model AFAIK. And despite they were assembled in Hungary, the nameplate on the back said Made in Japan.

    My VCR is wrinkling both edges of the tape, but the center of the tape is left perfectly intact. Someone told me it could be a "spindler", I'm a newbie so I have no idea what I could do to fix it. I'm currently looking for info to get some knowledge that would lead me to an answer.

    If I remember that's the stop position. Cassette down, unlaced. Normally you load the cassette basket to access the screws. I just push it slightly to access the screws and then pull it back to eject position.

    I have a General Electric VG-7720 (made by Panasonic in 1988) that, when fully rewinding a tape (which takes about 4½ minutes), starts making a loud noise about halfway through, which gets louder and higher pitched until it finishes rewinding. I've traced the noise to the nylon gear that drives the right-hand spindle (it isn't being driven when rewinding; it is just freewheeling). The gear starts vibrating when its RPMs reach a certain point and that's what's causing the noise. If I lightly press the back of my fingernail against the gear while rewinding (which prevents it from vibrating), the noise instantly stops, and when I remove my finger, the noise instantly returns. Do you think that putting some grease on that gear's shaft would dampen it to prevent the vibration? If so, what type of grease should I use? Also, do you know how to remove the gear? There's some type of tiny retaining clip/washer thing for it on top of the shaft, same idea as an E-clip, snap ring, etc., but I don't know exactly what it is nor what type of tool would work to remove it.

    @@12voltvids It's fixed! The little clip just pries off. I couldn't remove the gear nor the big belt pulley above it though because there was a metal tab in the way of both of them that seemed to be specifically designed to prevent them from being removed. I was able to lift the gear up enough to put some grease a little ways down into its center hole though, and when I just tested it, it was the first time I've heard it do a full rewind of a tape without squawking since the year 2000.

    Have no idea haven't seen that crap in 40 years. I know them to see them but which models use them i have no clue. Contrary to what sone may thing i really didn't pay much attention to consumer crap when I was fixing it. They all looked the same. I think most that were in the service business felt the same way. We didn't get excited by this stuff like users did. We just fixed one and moved on. No emotional attachment to any of this stuff.

    @@joeb2588 Well, maybe. I find that mechanisms with solenoids (the '80s, beginning of '90) are ususally very hard to service. They were quite nice to the tape but very clunky. So much room for a timing error. The G mechanism from the '80s had whopping 12 alignment points, whereas the Z mech has only 4. So if you prefer simplicity, go with the Z or K mech, you do not need to go ancient nowadays. A great SVHS machine are probably NB-HS860, NV-HS960 (Z mech) or NV-HS1000 (K mech). All of these have the TBC built in. Of course these are available in the EU, I do not know what is obtainable in the USA or Canada.

GE 1vcr6015B, was the model#. I loved that machine. It looked great, the remote was loaded with all sorts of functions, the effects were great. In fact, it was the best vcr I have owned. Sure I had others after that one but this one was special. Prob had the G mech? Either way, it was neat.

    i have 2 pv-8450s and a 8400 these blue line Panasonic vcrs run like a clock. as many older ones do along with sharp, symphonic and emerson vcrs, as my experiences. G mech machines where crap tho, as the planetary gear set would skip teeth and throw out timing. then the vcr would grind itself to an unrepairable death, (had two of those) panasonic should of used metal gears.
